[OpenBabel-scripting] Open Babel Warnings

[A. S. <oli...@ya...>]

I use OpenBabel Perl Module to parse mol files to a database and by the way I
use the following code to obtain smiles format:
	my $obMol=new Chemistry::OpenBabel::OBMol;
	my $obConversion=new Chemistry::OpenBabel::OBConversion;
	$obConversion->SetInAndOutFormats("mol","smi");
	$obConversion->ReadString($obMol,$mol_file);
	my $outSmiles=$obConversion->WriteString($obMol);

All works OK, but I obtain sometimes warning messages on screen that make
slower the process, I'd like to avoid this messages but I don't know how to
do that.

An example of the warning messages:
*** Open Babel Warning  in WriteMolecule
  1-[(4-Acetyl-phenylcarbamoyl)-methyl]-pyridinium Proton(s) added/removed

With the InChi format I have success avoiding this messages with this code:
	my $obMol=new Chemistry::OpenBabel::OBMol;
	my $obConversion=new Chemistry::OpenBabel::OBConversion;
	$obConversion->SetInAndOutFormats("mol","inchi");
	$obConversion->ReadString($obMol,$mol_file);
	$obConversion->SetOptions("w",1);
	my $outInchi=$obConversion->WriteString($obMol);

I want to know if exists a similar solution for smiles, because the former
doen't work ($obConversion->SetOptions("w",1);)

Thanks.
